A team of hundreds of physicists and astronomers have announced results from the largest-ever, three-dimensional map of distant galaxies, created to make one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the Universe.

“We have spent five years collecting measurements of 1.2 million galaxies over one quarter of the sky to map out the structure of the Universe over a volume… read more

Researchers at the University of California, Riverside have developed a transparent “window to the brain” — a skull implant that is biocompatible, infection-resistant, and does not need to be repetitively replaced.

Part of the ongoing “Window to the Brain” project, a multi-institution, cross-disciplinary effort, the idea is to use transparent skull implants to provide laser diagnosis and treatment of a wide variety of brain pathologies, including brain cancers, traumatic… read more

This is standardized survey of cellular-level activity in the mouse visual system. The goal is to empower scientists to “investigate how circuits in the behaving mouse brain coordinate to drive activity and perception, and lays a crucial foundation for understanding perception, cognition and ultimately consciousness.”

Juno Therapeutics, Inc. announced July 7 that it has received notice from the FDA that it has placed a clinical hold on an immune-cell cancer treatment known as the “ROCKET” trial, which was reported on KurzweilAI on Mar. 10, 2016.

The clinical hold was initiated after two patient deaths, which followed the recent addition of fludarabine to the pre-conditioning regimen. Juno has proposed to the FDA to… read more

Some birds have been found to be as intelligent as mammals. And some that can see ultraviolet (UV) light live in a super-sensory world apart, able to transmit and receive signals between each other in a way that is invisible to many other species.

Now the ability of finches, sparrows, and many other birds to see ultraviolet (UV) light is explained in a study published in the… read more

University of Minnesota (UMN) scientists and associates have developed new technology that can detect signs of Alzheimer’s before the onset of symptoms — early enough to give drugs a chance to work — in mice and humans by simply examining the back of their eyes.

Looking at Alzheimer’s effects through the eye is a key advantage of the new technology. “The retina of the eye is not just ‘connected’… read more

Washington University in St. Louis engineers have developed an innovatiave “bio-hybrid nose” that could be used in homeland security applications, such as detecting explosives, replacing state-of-the-art miniaturized chemical sensing devices limited to a handful of sensors.

Compare that to the locust antenna (where their chemical sensors are located): “it has several hundreds of thousands of sensors and of a variety of types,” says Baranidharan Raman,… read more

In Southeast Asia 50 per cent of the population may be positive for melioidosis; staph and acne bacteria may also end up in the spinal cord

July 11, 2016

Imagine a deadly bacteria that can be picked up by a simple sniff and can travel to your brain and spinal cord in just 24 hours. Or one that could just be quietly sitting there, waiting for an opportune moment. Or maybe just doing small incremental damage ever day over a lifetime … as you lose the function in your brain incrementally.

Neurons’ activity seemed to improve by adding IGF-1, which is known to enhance connections between neurons

Why do the brains of up to 30 percent of people with autism spectrum disorder grow faster than usual, early in life? A new study co-led by Salk Institute scientists has used a new stem cell reprogramming technique to find out.

Published July 6, 2016 in the journal Molecular Psychiatry, the Salk team found that stem cell-derived neurons made fewer connections in a dish compared to cells… read more

Could lead to bio-inspired microrobots that deliver drugs to target tissues

July 8, 2016

Hokkaido University researchers have designed a crystal material that continually flips between two positions like a paddle, propelling an attached structure, when stimulated by blue light. It could lead to bio-inspired microrobots that deliver drugs to target tissues, for example.

The team made azobenzene-oleic acid crystals, composed of an organic compound called azobenzene, commonly used in dye manufacturing, and oleic acid, commonly found in cooking oil. Azobenzene molecules… read more

Facebook began today (Friday, July 8) rolling out a new beta-version feature for Messenger called “Secret Conversations,” allowing for “one-to-one secret conversations … that will be end-to-end encrypted and which can only be read on one device of the person you’re communicating with.”

Facebook suggests the feature will be useful for discussing an illness or sending financial information (as in the pictures above). You can choose to set a… read more

May help develop future therapies and neuroprosthetic devices for paraplegic patients and amputees

July 7, 2016

École polytechnique fédérale de Lausanne (EPFL) scientists have invented a new robot called “Pleurobot” that mimics the way salamanders walk and swim with unprecedented detail.

Aside from being cool (and a likely future Disney attraction), the researchers believe designing the robot will provide a new tool for understanding the evolution of vertebrate locomotion. That could lead to better understanding of how the spinal cord controls the body’s locomotion, which… read more

JULY 8, 3:56 AM EDT — Livestreamed data from multiple users with cell phones and other devices could be used to help police locate shooters in a situation like the one going on right now in Dallas, says Jon Fisher, CEO of San Francisco-based CrowdOptic.

Here’s how it would work: You view (or record a video of) a shooter with your phone. Your location and… read more

Scientists from the Institut Pasteur and the CNRS have made the surprising discovery that new neurons formed in the olfactory bulb of adult mice are constantly reorganizing the billions of synaptic contacts they establish among themselves (also described as constant structural plasticity).

The researchers found this puzzling because constant structural plasticity is normally confined to specific critical periods after birth, and “plasticity in neural circuits… read more
